This book is dealing with fourteen chapters covering chemical and elemental composition of Earth and Earth crust; rocks and minerals, their weathering processes leading to soil formation; soil reactions (pH) and its buffering capacity; soil organic matter; inorganic soil colloids such as silicate clays and others; essential plant nutrients, their sources and transformation chemistry in soil; organic manures, chemical fertilizers and biofertilizers, ion exchange reactions and chemical equilibria in soil, soil biology and chemistry of related soil processes; soil erosion and its impact on soil fertility; problem soils such as acid soil, salt-affected soil, submerged or waterlogged soil. All these aspects have been dealt from chemistry point of view with sufficient explanation and mechanisms of certain processes, wherever it is applicable, in order to make the subject more meaningful, logical, simple, and understandable to the learners as well as the teachers. Finally, it deals with present day burning issue of environmental pollution due to intensive and extensive agricultural practices leading to soil contamination with pesticides, fertilizers, and other hazardous compounds which, in turn, cause air and water pollution too. With my vast teaching and research experience that started from 1985,

The book has been prepared in such a manner that students may find their all sorts of queries in soil science from chemistry point of view through a holistic approach. The chapters have been arranged systematically, so that the readers will enter the domain of soil chemistry in a proper way step by step.
